Chronostratigraphy on sediment core CRP-2 from the Ross Sea, Antarctica, supplement to: Lavelle, Mark (2000): Strontium isotope stratigraphy and age model for CRP-2/2A, Victoria Land Basin, Antarctica. Terra Antartica, 7(4), 611-619

Mark Lavelle
Strontium isotope stratigraphy was used to date 16 discrete horizons within the CRP-2/2A drillhole. Reworked Quaternary (<1.7 Ma) and possible Pliocene (<2.4 Ma) sediments overlie a major sequence boundary at 25.92 meters below sea floor (mbsf). This hiatus is estimated to account for c. 16 Myr of missing section. Early Miocene to ?earliest Oligocene (c. 18.6 to >31 Ma) deposits below this boundary were cut by multiple erosion surfaces of uncertain duration. Strontium isotope ages...
